Loom picker



Patented Oct. 21, 1941 fnooM PICKER Louis A. 'De'coning, woonsocketylt.71.1 Y -ApplicationAp1-il 1, 1939, Serial'Nq. 2 5,525] 1 01am. (01. 13960) This invention relates to an improved loom picker.

One object of the invention is to provide a loom picker which is formedof metal and is thus capable of use over longer periods of time than thecommon rawhide pickers now in use.

Another object of the invention is to provide a loom picker having aninterchangeable shuttle driving plug and, also, an interchangeablepicker rod sleeve, which plug and sleevemay easily be replaced at smallexpense, should they become worn.

A further object of the invention is to provide a device of thischaracter having curved driving surfaces for the picker stick so thatcramping of the stick will not take place.

Another object of the invention is to provide a loom picker havingguiding surfaces which will assure movement of the picker in a straightline.

And a still further object of the invention is to provide a loom pickerwhich will be characterized by the utmost simplicity and which may bemanufactured cheaply.

Other objects of the invention will become apparent during the course ofthe following description.

Referring now to the accompanying drawing:

Figure l is a top plan view, partly in section, of my improved picker.

Figure 2 is an end view of the device, the end of a picker stick beingshown in position in dotted lines.

Figure 3 is a sectional view on the line 33 of Figure 1, looking in thedirection indicated by the arrows.

Figure 4 is a side elevation showing a slightly modified form of drivingplug.

Referring now more particularly to the accompanying drawing, whereinsimilar reference numerals designate like parts throughout the variousviews, the numeral l indicates, in general, the body of my improved loompicker. The loom picker is preferably formed of high grade aluminum andincludes an enlarged portion 2 which extends throughout substantiallyhalf the length of the body. The body is reduced in width and thicknessto define a reduced shuttle driving portion or web 3. It should beunderstood that, while the body is preferably formed of a special highgrade aluminum, any suitable light weight metal may be employed.

The shuttle driving portion 3 of the body I is formed with an enlargedcircular end having a bore or socket 4 which extends laterallythroughout the major portion of the width of said portion 3. Removablyfitted in the bore 4 and extending forwardly thereof is a driving plug 5which is formed. of relatively soft material such, for example, asrawhide. The plug 5 will, of course, be engageable with the end of theshuttle for driving said shuttle at the forward movement of the pickerstick.

The body I is provided, medially of its width, and at the inner of theenlarged portion 2, with a slot or opening 6 which is adapted toaccommodate the end of a picker stick, shown in dotted lines at 1, inFigure 2, therethrough. The opening 6 is formed with curved bearingsurfaces 8 and 9 at its ends and said opening is formed with straightsides l0 and l I. The hearing surfaces 8 and 9 serve the purpose ofpermitting free swinging movement of the picker stick I in the slot oropening 6. Injury to the picker stick will thus be prevented and, ofcourse, full swinging movement of said stick will be permitted so thatfull efficiency will be assured. The result of the maximum efficiencyfor the picker mechanism will, of course, be that less work for loomfixers will be necessary. Smashes, with resulting cloth damage, willalso be greatly reduced, as will be the frequency of picker stickbreakings. The bearing surfaces 8 and 9, being curved as shown, willprovide three times as much surface for the picker stick as comparedwith pickers now in use. As stated, a perfect bearing for the pickerstick is provided so that injury to said stick will be effectuallyprevented.

Formed in the enlarged portion 2 of the body I, in spaced relation tothe slot or opening 6, is a picker rod opening l2. The picker rodopening extends throughout the entire width of the body and is open atboth ends. The picker rod opening removably receives therein a pickerrod sleeve I3, and said sleeve slidably receives therein a picker rodl4. Angular guide shoulders having flat bearing surfaces I5 are formedat the junction of the enlarged portion 2 with the reduced portion orweb 3, and said guide or bearing surfaces, as best seen in Figure 3,slidably engage the box back shown in dotted lines at l5 in Figure 3.Cramping of the picker 'will be avoided and straight movement of saidpicker thus assured.

Referrng now to Figure 4 of the drawing, the numeral l6 designates aslightly modified form of driving plug. The driving plug [6 has arelatively large head I! and a reduced portion l8. The plug 16, like theplug 5, may be readily re- Having thus described the invention, what I Jcontinuous curved bearing surfaces extending claim is:

As a new article of manufacture, a. picker for looms comprising a onepiece body portion having its opposite ends provided with thickenedportions of difierent lengths, one of which has an opening extendingentirely therethrough and 20 adapted to receive a picker rod and theother provided with a socket adapted to receive a driving plug, saidthickened portions being connected by a flat integral reduced web havingits end walls converging in the direction of the socket and definingoppositely disposed angular guide shoulders having flat bearing surfacesfor engagement with a loom box, there being a longitudinal slot formedin the long thickened portion adjacent the picker rod receiving openingand adapted to receive a. picker stick with one side wall of the slotdisposed in longitudinal alinement with the flat bearing surfaces of theangular guide shoulders, the oppostie end walls of the slot beingrounded transversely to form Q the entire width of the long thickenedportion l and--intersecting said angular guide shoulders for contactwith said picker stick.
